當提示：
[root@localhost ~]# ipmitool sdr
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No
such file or directory
Get Device ID command failed
Unable to open SDR for reading
需要添加如下：
[root@localhost ~]# modprobe ipmi_watchdog
[root@localhost ~]# modprobe ipmi_poweroff
[root@localhost ~]# modprobe ipmi_devintf
[root@localhost ~]# modprobe ipmi_si
[root@localhost ~]# modprobe ipmi_msghandler
當添加ipmi_si時，提示：
FATAL: Error inserting ipmi_si (/lib/modules/2.6.9-5.ELsmp/kernel/drivers/char/ipmi/ipmi_si.ko): No such device
這是因爲機器上沒有IPMI設備而出現的報錯。
